WILLIAM WEINMANN, OF PREAKNESS, NEW JERSEY.

MEDICINAL APPLICATOR.

Application filed November 10, 1924. Serial No. 748,898.

To all whom it may concern:

strands saturated with a suitable medicant,

in canals or passages. The present invention is intended primarily for inserting a medi cated strand into themill-z canals of cows teats, to reduce inflammation.

The object of the invention is to provide an improved form of applicating stem which is so constructed as to expand the canal or passage as it is inserted, insuch a manner as to overcome any possibility of the front end of the stem catching on and injuring the membrane.

With the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Figure 1 is a side elevation.

Figure '2 is a sectional view through the front end of the applicator partly in elevation.

Figure 3 is a view similar to Fig. 2, illustrating a strand engaged with the plicator, preparatory to insertion into canal.

Figure t is a sectional vie-w partly in elevation showing'the manner of inserting the applicator and the strand into the teat.

The numeral 1 designates a preferably straight stem which may be formed of steel or any other appropriate material, said stem having a rounded end 2 Whose front exbut apthe tremity is formed with a transverse groove 8 into which the intermediate portion of a medicated strand 4 is seated, the ends of the strand being brought rearwardly along opposite sides of the stem as shown. 50 Immediately in rear of the rounded end 2, but rearwardly spaced to some extent therefrom, the stem 1 is formed with an integral, enlarged head 5 having a rounded periphery. When inserting the 5 device, this enlarged head expands the canal or passage and thus effectively opens it up, in advance of the stem, so that there is no chance of the front end of said stem catching upon and injuring the membrane of the passage. After the strand has been inserted to the proper extent, the applicator is With-. drawn, leaving said strand in place, and after it has remained in the passage for the desired length of time, it is withdrawn.

The inventionQis simple and inexpensive and it is well adapted for treating inflammation in the milk canals of cows teats, but it will be obvious that it is not restricted to this particular field of use.

I claim:

A stem applicator comprising a needle shaped stem for insertion into a passage to be treated, said stegn having a rounded front end formed with a transverse groove to re- 7 ceive a medicated strand, and an enlarged head on said stem immediately in rear of but rearwardly spaced from said rounded end, said head being adapted to expand the passage into which the stem and strand are inserted and thus prevent said rounded front end of the stem from injuring the membrane of such passage, the entire applicator being adapted to withdraw from the medicated strand, leaving the latter in the passage, 85 when the applicator is removed from said passage.

In testimony whereof I have hereunto af fixed my signature.

VILLIAM WEINMANN.
